To @ZZ wiz/0m t waa/y concern,.-

Be it known that we, ROBERT HILLIs, re-

siding at East Orange, in the county of Essex and State of New Jersey, and WILLIAM J AMES HILLIS, residing in the borough of Brooklyn, city of New York, in the county of Kings and State of New York, citizens of the United States, have'invented certain new and useful Improvements in Gas Pressure Regulators and Governors, of which the following, taken inl connection with the accompanying drawings, is a full, clear, and exact specification.

This invention relates to devices employed for regulating the pressure and governing the How of gas from a gas-meter.

The object of our invention is to provide or produce a simple, cheap, reliable, durable, and efficient gas-pressure regulator and governor, which may be easily and quicklyvapplied in connection with the gas service-pipe and with the outlet from the meter and which will operate to eifectually regulate the pressure of the gas in the service-pipe and govern or control the iiow of gas when at the desired pressure.

To accomplish all of the foregoing and to secure other andfurther advantages in the matters of construction, operation, application, and use, our improvements involve a new and useful device of which the parts are peculiarly constructed and arranged, as will be herein first fully described and then pointed out in the claim.

In the accompanying drawings, forming part of this specification, Figure 1 is a front elevation showing an ordinary form of gasmeter with our improved pressure-regulator and governor connected with the outlet-pipe and with the service-pipe leading from the meter, a portion of the applied device being shown in section. Fig. 2 is a vertical view, partly in section and partly in elevation, on a scale enlarged beyond that of Fig. 1 and showing the construction and arrangement of the regulator and governor and the couplings or union`s connected therewith. Fig. 3 is a horizontal section and plan view on a plane through line 3 3 of Fig. 2 and looking in the direction of the contiguous arrow. Fig. 4 is a horizontal section and plan view on a plane through line 4 4 of Fig. 2 and looking in the direction of the contiguous arrow.

In all the figures like letters of reference wherever they occur indicate corresponding parts.

A represents any ordinary form of gasmeter, of which B is the inlet-pipe, and O the outlet-pipe.

D is the gas service-pipe intended to be eX- tended, as may be desired, and to convey the gas to the point or points of consumption after it has passed through the meter.

We find it most advantageous to apply our improved regulator and governor near the meter; but of course it might be applied at any other desired point in the service-pipe between the meter and the first burner or first branch 5 but the nearer it is to the meter the better it will regulate the pressure and govern the flow of the gas.

E is a short section of gas pipe or tubing, the same being threaded at both ends and of about the same diameter as the service-pipe to be employed. Fitted within this section E and capable of easy removal therefrom is an interior tubing F, of metal or other suitable substance which is not affected by the gas. Arranged in the tube F in a permanent or semipermanent manner are a number of disks of metal or other suitable material, and

`these disks are preferably four in number,

although there might be more and in some cases less than four. The disks are represented at G, H, I, and K, and they are concaved on one side and provided with perforations for the passage of gas through them, being separated by about equal distances within the tube F. The perforations through the disks vary in size and number, according to the circumstances of each particular case, the disk having the largest number and the largest size ofl perforations being located nearest the meter, the disk with the neXt largest number and largest size of perforations being next beyond the first one, and so on to the end of the series. Thus it willbe seen that the disks are graduated from the first to the last of the series. The disks are of equal diameter, and they are forced into the interior cylinder from either end thereof and are held in place, by frictional contact with the inner smooth surface of said cylinder, the inner and outer cylinders being both imperforate. The concaved form of the disks insures a suficiently-tight fit within the interior cylinder, and being uniformly circular and of equal diameter they are all made with one tool and require no other special fitting or formation.

In the particular example selected for illustration it may be assumed that there are four burners to be served through the service-pipe. In such case we preferably make the final disk in the series with four small perforations, as at a a, of size so that the requisite amount of gas under the required pressure will pass through the four orifices. The next disk II may have six perforations, preferably a trifle larger than those in the disk G. The disk I may have eight perforations, preferably a tri'lie larger than those in the disk H, and the diskK may have twelve perforations, as at b l), preferably larger than those in the disk I. We do not, however, desire to be un-` derstood as being confined to these particular numbers or to the particular sizes indicated, for obviously the number and sizes of perforations might be varied and similar results secured. For instance, for a two-burner service the last disk in the series may well be provided with but two perforations, and the last disk may have three or more perforations according to the number of burners to be served but with the device arranged to operate in accordance with our invention` it will be understood that when the gas is flowing through the regulator and governor it will first be impeded somewhat by the first disk. I-Iaving passed the first disk, it will be again further impeded by the second. Having passed the second, it will be again further impeded by the third, and similarly for the fourth, and when it passes through the latter it will be only ca able of iiowing at the desired rate for which the last disk was constructed. The series of disks with perforations of varying numbers and varying sizes operates to break up the otherwise free iiow of the gas through the section E, and thus not only to regulate the pressure in the service pipe and keep it practically uniform, but to govern the amount of pressure of the issuing gas, and therefore the amount of iiow from the meter into the service-pipe.

The advantages of the improved combined regulator and governor, so far as its use is concerned, are to afford a steadyfloyir of gas to the burners and to maintain tliepressure at the burners at the required degree, whereby there is insured not only a steady illumination, but an leconomical consumption of gas. The pressure of gas on the mains or inlet-pipey to the meter may be increased to a considerable extent; but with the improved device in place this increase of pressure will not materially increase the amount of gas which will pass through the meter.

We preferably employ an ordinary pipeunion at one end of the section E, as at L, and a cou ling-union at the other end, as at M, by which to properly locate and secure the improved device in position for use.

The inner tube or sleeve F may be easily withdrawn and replaced by another with the proper number and arrangements of disks whenever so desired.

Being constructed and arranged substantially in accordance with the foregoingy eX- planations, our improved device will be found to answer all the purposes or objects of the invention hereinbefore alluded to.

Having now fully described our invention, what we claim as new herein, and desire to secure by Letters Patent, is-

The herein-described gas regulator and governor, the same being composed of an outer imperforate cylindrical tube-section having threaded ends, an inner removable imperforate cylindrical tube-section, a series of perforated and concaved disks of equal diameters located in the inner tube-section and frictionally held in place therein, the perforations in the disks var ing both in size and in number from the beginning to the end of the series, and threaded unions for removably coupling the device with a meter and with a gas service-pipe, substantially as shown and described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
